In whom are hid all the treasures of wisdom and knowledge. This may be understood either of the mystery of the Gospel, which contains the rich mines and hidden treasures of all divine truths; so called, because of the richness and intrinsic value and excellency of them; and because of their variety and abundance, being the unsearchable riches of Christ: or of Christ himself; and not so much of his personal wisdom, either as God, being the all-wise God, the wisdom of God, an omniscient Being, that knows all persons and things whatever, within the whole circle of wisdom and knowledge; or as man, whose wisdom and knowledge, though created, was very large and abundant; or as Mediator, on whom the spirit of wisdom and understanding, of counsel and of knowledge, rests; but of that fulness of truth as well as grace, which dwells in him as in its subject and fountain; by whom it comes, and from whom it is derived unto us; and our highest wisdom and knowledge lies in knowing him, whom to know is life eternal; and the excellency of whose knowledge surpasses everything else; it is the greatest riches, and most valuable treasure; nor is there anything worth knowing but what is in Christ, all is laid up in him: and being said to be "hid" in him, shows the excellency of the wisdom and knowledge that is in him only valuable things being hid, or compared to hid treasure; that this cannot be had without knowing him; that it is imperfect in the present state, and is not yet fully and clearly revealed; and therefore should be inquired after, and searched for, and Christ should be applied unto for it: atmkx yznn, "treasures of wisdom", is a phrase used by the Targumist .
